The Notes have an Issue Date of June 30, 2026 and a Maturity Date of July 1, 2031 and pay a variable monthly-equivalent coupon based on observation-date tests.

If on an Observation Date every Underlier is at or above its Coupon Barrier Value you receive the Higher Coupon Amount of $8.75 per $1,000; if any Underlier is below its Coupon Barrier Value you receive the Lower Coupon Amount of $0.208 per $1,000.

The Initial Issue Price is $1,000 (100%) per Note, with an agent commission of 4.10% and proceeds to Barclays of 95.90%.

Barclays Bank PLC is offering contingent income auto-callable securities due June 15, 2028 linked to the worst performing of Amazon (AMZN), Alphabet (GOOGL) Class A and Microsoft (MSFT). Each security has a stated principal amount of $1,000 and a contingent quarterly payment that will be set on the pricing date and will be at least $27.50 (at least 2.75% of principal) if, on a determination date, each underlier is ≥ the downside threshold (50% of its initial underlier value).

Automatic early redemption occurs if, on any non-final determination date, every underlier is ≥ its initial underlier value; otherwise investors remain exposed at maturity to the worst performing underlier. If the worst performing final underlier is below its downside threshold, the maturity payment equals the stated principal multiplied by that underlier's performance factor and could be less than 50% of principal or zero. Payments are unsecured obligations of Barclays and subject to Barclays' credit risk and potential exercise of U.K. Bail-in Power.
